Uncle Wang, a 37-year-old smoker. In his eyes, cigarettes are a good thing, and the sentence “a cigarette after a meal is like a fairy” is not wrong at all.

He often used himself as an example, “I’m 62 years old and don’t have cancer at all. Don’t ask me to quit smoking. It’s all a lie.” In addition, the pictures of “black lungs” of long-term smokers circulating on the Internet are not believed by Uncle Wang. He thinks that after a few years, he will get tired of smoking, and the lungs will turn white after quitting smoking.

“pulling” 1 million Chinese people every year

If smoking continues to worsen, by 2050, tobacco-related diseases are expected to kill 100 million, 50% of whom will Died at 35-60 years old.

Smoking affects lung function, destroys the complete structure of the lung, weakens the function of the respiratory system, and causes chronic obstructive pulmonary disease, lung cancer and other diseases.

smoking is lung cancer Zhang Jie, director of the Testing Center of Peking University Third Hospital, pointed out that the more smoking, the higher the risk of cancer. People who smoked 20 cigarettes a day for more than 20 years had a 20-fold increased risk of dying from lung cancer.

Smoking affects not only oneself but also others. Women who live with smokers have a six-fold higher risk of developing lung cancer. Compared with men, women who smoke have a greater risk of developing lung cancer, 1.9 times that of men.

If you quit smoking early, you can effectively reduce the risk of lung cancer. A study in the United States found that smoking cessation for 5 years significantly reduced the risk of lung cancer in smokers.

Researchers at Vanderbilt University School of Medicine followed 8,907 participants for decades, and 284 were eventually diagnosed with lung cancer. Of the 284 lung cancer patients, 93% were heavy smokers, smoked at least 1 pack a day, and smoked for more than 21 years. But if heavy smokers quit smoking for 5 years, their risk of developing lung cancer is 39% lower compared with those who still smoke.

The risk decreases as you quit smoking.

Can black lungs turn white after quitting smoking?

With the increase of smoking and the prolongation of smoking age, the lungs will become darker and darker. Because cigarette smoke contains more than a billion dust and particles, when the dust and particles are inhaled in the lungs, the mucus secreted by the alveoli will stick them and then excrete them through the cilia in the lungs. If you smoke a lot for a long time, the cilia in the lungs will continue to work, and the damage will become more and more serious. It keeps building up in the lungs, eventually turning them black.

So, can the lungs come back white after quitting smoking?

After quitting smoking, the self-cleaning function of the lungs will improve and the mucus secreted by the trachea will decrease , breathing becomes easier, and lung cilia are better able to remove dust and particles. At the same time, the immune system in the alveoli can kill more pathogens and reduce disease.

Of course,lungs will also slowly whiten, but it’s hard to get back to their original shape< span>. Especially for smokers who are older and have been smoking for a long time, too many harmful substances have been deposited in the lungs, which is difficult to eliminate. In addition, part of lung damage caused by long-term smoking is difficult to reverse, such as permanent enlargement of alveoli and alveolar ducts, fibrosis of bronchial walls Thickness, hyperplasia of glands, etc.

Scientists found that after 4 weeks of quitting smoking, 49% of those who quit smoking immediately 39.2% of the quitters in the tapering group did not relapse; at 8 weeks of quitting, 36.6% of the quitters in the immediate quit group did not relapse, and 29.2% of the quitters in the tapered group did not relapse. At 6 months of quitting,22% of the quitters in the immediate withdrawal group did not relapse, and 15.1% of the quitters in the tapering group did not relapse.
